That’s why you can see the “Update VMware Tools” option instead of the “Install VMware Tools” option in the tool menu. When you update the virtualization program installed on your host computer, the integrated VMware Tools ISO file is also updated automatically. However, it is recommended to install the drivers for your guest system using the darwin.iso file downloaded with VMware Unlocker, which you used when installing a macOS version with VMware Workstation. In order to install drivers in the macOS guest operating system running on VMware virtualization software, you can install with the existing ISO file in the software by clicking “Install VMware Tools” from the tool menu of the software.
